1. 1. Mechanistic Studies On the Role of Polyamines and Microvesicles in Tumor Growth and Hypoxia-mediated Angiogenesis

   Författare :Katrin Svensson; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; angiogenesis; hypoxia; microvesicles; exosomes; polyamines; tissue factor; coagulation;

   Sammanfattning : Solid tumors are composed of cancer cells, as well as resident or infiltrating non-malignant cells that contribute to the malignant state in an ecosystem generally accepted as the tumor microenvironment. Microenvironmental tumor hypoxia is the foremost leading cause of angiogenesis, i.e. LÄS MER

3. 2. On the Role of Polyamines and Microvesicles in Tumour Development. Regulation by Hypoxia and Implications for Therapeutic Intervention of Cancer

   Författare :Johanna Welch; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heparan sulphate proteoglycans; cancer; hypoxia; polyamines; microvesicles; anti-angiogenic therapy; angiogenesis;

   Sammanfattning : Novel strategies for specific tumour cell targeting are necessary in order to improve survival rates and to reduce side effects of current therapies in cancer patients. Hypoxia is a hallmark of solid tumours and one of the major driving forces for tumour progression. LÄS MER

4. 3. Mechanisms of Shiga toxin-mediated signaling and toxicity

   Författare :Karl Johansson; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EHEC; Shiga toxin; Microvesicles; Purinergic Receptors;

   Sammanfattning : AbstractShiga toxin (Stx) is the main virulence factor of enterohemorrhagic Escherichia coli (EHEC). EHEC strains cause gastrointestinal infection and release Stx that can gain access to the circulation. Patients may develop hemolytic uremic syndrome with extensive kidney damage. LÄS MER

5. 4. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

   Författare :Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

   Sammanfattning : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

7. 5. Studies of the pathogenesis of Shiga toxin-producing Escherichia coli-induced hemolytic uremic syndrome

   Författare :Ida Arvidsson; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EHEC; hemolytic uremic syndrome; Shiga toxin; complement; hemolysis; microvesicles; cathelicidin;

   Sammanfattning : Hemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia and acute kidney failure. The most common form of HUS is associated with gastrointestinal Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) infection. EHEC are non-invasive strains with Shiga toxin as the unique virulence factor. LÄS MER
